What is ECDIS?

ECDIS is an acronym for “Electronic Chart Display and Information System”, which is a computer based system for displaying charts and navigational data. The term, ‘ECDIS’ is used solely for those chart systems that comply with IMO (International Maritime Organization) recommendations.

ECDIS units are connected to onboard navigation systems such as, GPS, Gyrocompass and depth sounders to provide real-time data to the chart displayed on the screen. By expanding the ECDIS interface to include the radar and AIS; radar overlay, ARPA and AIS targets can also be displayed.

There are two main chart types used in ECDIS; the vector chart (ENC chart) is a digital database of a chart containing all information necessary for safe navigation. The ability to turn on and off certain details and to set danger zones etc is a feature of the vector chart. The Raster chart (ARCS chart), is an alternative to the vector chart and is a scanned digital image of a paper chart.

It would appear that the ECDIS is replacing the traditional paper chart for navigation, however a back up ECDIS is always required and some authorities insist on paper charts. It is always prudent to check with the relevant authorities on ECDIS carriage requirements.
